Turkish PM to return government mandate to president - AKP official

ANKARA, Aug 18 (Reuters) - Turkish Prime Minister Ahmet
Davutoglu will return the mandate to form a government to
President Tayyip Erdogan on Tuesday evening after the ruling AK
Party's coalition talks with opposition parties collapsed, an
AKP official told Reuters.

Erdogan could dissolve Davutoglu's caretaker cabinet and
call for the formation of an interim "election government" if no
deal is reached by Aug. 23. That would mean power being shared
between all four parties before a snap election in the autumn.
